You will have to have Stop A repeate as many times as your application requires. So either Load it in multiple times, or load it once (first stop) and copy/paste it in many times and then set the Routename field (calc) to the ObjectID. Now you can load your stops B, C, etc with routename 1, 2, 3, etc and things will all match up. If you need to use traveling salesman, where you will have multiple sets of stops per route, each starting with A, then load as above and on the Route properties, Analysis Settings tab, check on "Reorder Stops To Find Optimal Route" and un-check the "Preserve Last Stop". This way, the first Stop A for each unique Routename will be the starting stop and the rest of the stops in that route will be re-ordered for optimal sequence. Jay Sandhu ... View more

You can create a route layer and load it with pairs of stop, A to B and A to C using the ROUTENAME property so that you will have two routes solved in one route layer (you can load more stop sets). Now when you solve, you will get two routes, A to B and A to C.  You can then run this addin http://resources.arcgis.com/gallery/file/ArcObjects-.NET-API-Code-Gallery/details?entryID=C8A2186E-1422-2418-3494-48812C8DB8DE to create a line feature class from the "traversal" which is kept in memory. That is, it will add a Lines feature class that has every edge traversed per route. Now you can open the Line attribute table and the EID column contains the ID of the Edge traversed. Right-click on this field and choose "Summerize" and it will create a dbf file with each edge and how many times it was traversed by the routes. Jay Sandhu ... View more

First make sure you are using AnyVertex connectivity if you have data from OSM. You could do a service area lines to see what is connected to your starting facility location and select those features and reverse the selection. Or you could make geometric network on that data and use one of the Utility Network Analysis toolbar options to find disconnected portions: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//002r00000033000000.htm Or you could use an ArcObjects sample to do this: http://help.arcgis.com/en/sdk/10.0/arcobjects_net/conceptualhelp/index.html#/Custom_Solver/000100000n99000000/ Jay Sandhu ...

Most likely you are out of memory due to the large number of facilities/break value you are using. See the following for simillar issue: http://forums.arcgis.com/threads/3370-Network-Analyst-Error-The-geometry-is-not-Z-aware Jay Sandhu ... View more

How big is your service area break? It is likely that you are not getting any output as the solver may have run out of memory trying to solve for such a large number of locations. You can either solve for smaller set or use the idea of "chunking" or setting up a registry key to tell the solver to solve a few at a time and write them out. You can follow the directions here: http://support.esri.com/en/knowledgebase/techarticles/detail/38426 As far as the other messages about non-traversable, your facilities are getting located on restricted edges. You could take a look at the restrictions that are on and turn some of them off (if permitted) or locate these locations some other nearby streets. Regards, Jay Sandhu ... View more

Basically Add the required fields to the Lines table, set up a Join to Origins (or Destination) table and Calc the vaues over. You can add a Fields like AddressID and NeighbourID to the Origins table when you First create the OD layer. Then when you do a Load Locations to load the Origins, you can MAP over the AddressID field from your Point feature class over to the newly added AddressID field (same for the NeighbourID) and now these values will be loaded over to your Origins table. After the solve, add the same fields to your Lines and set up a join based on the OriginID on Lines and ObjectID on the Origins table. And then use the field calculator to populate the values for AddressID. You can read more on load locations here:http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/in_ArcMap/00470000003t000000/ Jay Sandhu ... View more

As I mentioned in my previous post, read the other other thread where I provided two ways to solve this including doing Joins. Jay Sandhu ... View more

I have replied to this in the other thread: http://forums.arcgis.com/threads/37655-Finding-all-links-in-a-route?p=135000&posted=1#post135000 Basically use the traversal result addin from the ArcGIS resources to get to the table of all the edges traversed. Jay Sandhu ... View more

If the street network data you are using is your own data, then you could add another impedance attribute based on the pollen values. Then solve the path but ACCUMULATE the pollen attibute. That is on the CF layer properties, there is an accumulation tab and you can check on the attributes you want to accumulate. As far as where is the Edges table, normally it is in memory and not exposed. You have to run the traversal code as described in the AddIn you download and then it adds it to the ArcMap table of contents. So you solve the CF and then run the AddIn. Once you have the Edges table, it has the OID of the streets. You can join it to that streets feature class and copy over your TOID to the edges table. Then you can Join it to your external table based on this TOID. But the first suggestion, add your external pollen count to the streets table and use that to create an impedance attribute and then simply accumulate is the easiest. Jay Sandhu ... View more

Increase the capacity of your vehicle! By default when you create a route, the MaxOrder Count is set to 30. So bring up the properties of your "vehicle" or route and change this number to be larger than 671. Jay Sandhu ... View more

Deb, ArcGIS comes with a Data and Maps DVD which has the street network for the entire USA. This is in a compressed SDC format and is ready for use with Network Analyst. You can use that for generating service areas. If you cannot locate your DVDs here is a blog that talks more about it: http://blogs.esri.com/support/blogs/mappingcenter/archive/2011/06/07/esri-data-and-maps.aspx Jay Sandhu ... View more

Network Analyst can be used to route within buildings modeled as 3D networks. There is a tutorial dataset that you can use and see how it is set up to model the stairs, elevators, etc: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00470000005q000000.htm You can also read a blog that talks about this capability: http://blogs.esri.com/dev/blogs/arcgisdesktop/archive/2011/05/27/what-do-you-get-when-you-cross-the-3d-analyst-extension-with-the-network-analyst-extension_3f00_.aspx Jay Sandhu ...

The query builder option is there for exactly this purpose, that is. to exlude locating on certain edges. There is no other simple solution to locate on some other edge that is not restricted. Jay Sandhu ... View more

Keep in mind these tools are for "geometric" networks and not Network Analyst. Geometric networks are for modeling utility (electric, sewer) and stream networks where flow direction and upstream and downstream concepts are modeled. You can interact with the geometric networks with the utility network tool bar. This forum is intended primarily for Network Analyst that operates on a Network Dataset and is geared for transportation networks. Jay Sandhu ... View more

The SDC is a read only dataset. You can not modify it. You mention the reason to create a new one for dissolve is performance, can you tell us which solver you are using and what is the performance and what performance you want to achieve? Jay Sandhu ... View more
